I currently have 4 lights which are operated by one light switch. From
what I can tell, the light are in a series (that is, they are all on
one circuit). I would like to keep the current light switch to operate
two of the lights and then install another switch to operate the other
2 lights. Is this possible? Can the new installation be part of the
same circuit? How would I go about doing this. Any help is
appreciated. Thanks in advance.
